An occupant protection device for a vehicle includes a collision predictor, a main airbag, and a deployment controller. The collision predictor is configured to predict a collision of the vehicle. The main airbag is configured to deploy toward an occupant from a front of the vehicle when a collision of the vehicle is predicted by the collision predictor. The main airbag includes a first deployment part, an arm-push-away deployment part, and a second deployment part. The controller is configured to cause the main airbag to deploy toward the occupant when a collision of the vehicle is predicted by the collision predictor. The controller is configured to, when a collision of the vehicle is predicted by the collision predictor, cause the first deployment part to deploy, subsequently cause the arm-push-away deployment part to deploy to push an arm of the occupant away, and thereafter, cause the second deployment part to deploy.

An airbag device of the disclosure includes an airbag module that is installed in a central region of a steering wheel of a vehicle, and that accommodates an airbag that can deploy behind the steering wheel when a driver is seated in the driver's seat. The airbag module has an airbag inflation control unit that controls an inflation direction of the airbag in such a manner as to allow the airbag to inflate above the airbag module, after the airbag has inflated in such a direction as to abut on the driver's chest at the time of deployment of the airbag.

A side airbag (SAB) of a vehicle includes: a main chamber disposed in a seat to be deployed from a side surface portion of the seat and, when deployed, configured to cover at least one of a thoracic region, an abdomen region, or a pelvis region of an occupant; a main inflator configured to supply gas to the main chamber to deploy the main chamber; and an auxiliary chamber communicating with the main chamber to allow the gas inside the main chamber to be supplied to an interior of the auxiliary chamber and connected to the main chamber to be deploy above the main chamber.

A pedestrian airbag device includes an airbag and an inflator that supplies an inflating gas to the airbag. The airbag includes a cowl cover portion and two pillar cover portions. The inflator includes a main body portion having a substantially columnar outer shape, and a mounting bolt disposed to protrude from an outer peripheral surface of the main body portion in an axis orthogonal direction of the main body portion. The main body portion is mounted on an accommodation site side by using the mounting bolt in a state where the main body portion is inserted into the cowl cover portion while an axial direction is disposed to substantially extend along a left-right direction. A gas flow regulating member suppressing a rearward outflow of an inflating gas discharged from the main body portion is disposed at a position on a rear side of the main body portion inside the cowl cover portion.

A pedestrian airbag device includes an airbag and an inflator that supplies an inflating gas to the airbag. In the airbag, an insertion opening portion for inserting the inflator into the airbag is disposed on the vehicle body side wall portion side. The insertion opening portion includes an insertion slit for inserting the main body portion of the inflator, and an insertion hole for causing the mounting bolt of the inflator to protrude. A guide tether for guiding when the inflator is inserted is disposed inside the airbag so that one end side is joined to the pedestrian side wall portion side, and the other end side is joined to a region on a side from the insertion hole in a peripheral edge of the insertion slit on the vehicle body side wall portion side.

The invention relates to an airbag module (10) for a vehicle occupant restraint system (12), comprising an airbag (14), an inflator (18), a shaping tether (22) for influencing the airbag deployment geometry which is connected to the airbag (14) at one tether end, and comprising a port release tether (20) which is connected to a discharge port closure (26) of the airbag (14) at one tether end, wherein the port release tether (20) is connected to the discharge port closure (26) so that it releases a discharge port (28) of the airbag (14) from a predetermined tensile tether force, and wherein an activatable tether release device (24) coupled both to the shaping tether (22) and to the port release tether (20) is provided for actively releasing the tethers (20, 22). Furthermore, the invention relates to a method of operating a vehicle occupant restraint system (12) comprising said airbag module (10), wherein airbag deployment takes place in response to predetermined basic conditions, such as in response to the weight of a vehicle occupant (16) and/or of a driving mode for manual or automated and, resp., autonomous driving.

An airbag apparatus of a vehicle may include an airbag cushion mounted in a rim which is necessarily provided even if the shape of a steering wheel is diversified, so that the airbag cushion is applied to steering wheels having various designs, whereby a driver is protected.

A seat airbag for a vehicle includes: a cushion including: a main part provided along an edge of a seatback of a vehicle, the main part spreading to a front part of the seatback so as to cover a passenger when spreading and open on a front part of the main part while covering opposite side parts and an upper part of the passenger; and an extension part connected to an open front end of the main part and shrinking so as to protect a front part of the passenger; and a protection tether connected to the extension part and shrinking the extension part by pulling the extension part during spreading of the main part.

A front airbag device for a vehicle is proposed. In the front airbag device, an airbag cushion is mounted in front of a passenger and is expanded to be positioned at a front surface of the passenger, a triangular main tether and a triangular support tether are positioned inside the airbag cushion, and one side of the main tether and one side of the support tether are spaced apart from each other and are coupled to the airbag cushion in a sewn manner, so that the main tether and the support tether support a front surface portion of the airbag cushion to protect a front surface of the passenger.

An airbag apparatus may include an airbag module mounted at a lower end portion of a crash pad; an airbag cushion configured to deploy from the airbag module to deploy in a space between a knee portion and a head portion of a passenger, wherein a tether is connected to the airbag cushion in a deployment direction of the airbag cushion toward at least one of the knee portion, a chest portion, and the head portion of the passenger to form an integrated deployment shape of the airbag cushion; and a release device connected to the tether close to the airbag module, and operated to allow the tether to be released or maintained in a fixed state in a deployment process of the airbag cushion depending on a body shape of the passenger on a seat of the vehicle.
